Debian is an open source operating system, which can be used for both desktops and servers, with an emphasis on stability and security. It is therefore used as the basis for various Linux distributions, including Ubuntu and Linux Mint. Version 11.x, codenamed ‘Bullseye’, is a so-called Long Term Support release and will be provided with updates over the next five years. More information about version 11 can be found on our front page. The release notes for this third update can be found below:

Updated Debian 11: 11.3 released

The Debian project is pleased to announce the third update of its stable distribution Debian 11 (codename bullseye). This point release mainly adds corrections for security issues, along with a few adjustments for serious problems. Security advisories have already been published separately and are referenced where available.

Please note that the point release does not constitute a new version of Debian 11 but only updates some of the packages included. There is no need to throw away old bullseye media. After installation, packages can be upgraded to the current versions using an up-to-date Debian mirror.

Those who frequently install updates from security.debian.org won’t have to update many packages, and most such updates are included in the point release.

New installation images will be available soon at the regular locations. Upgrading an existing installation to this revision can be achieved by pointing the package management system at one of Debian’s many HTTP mirrors†
